We’ve long known that some types of bacteria help you stay healthy. But now it appears that some types may actually help make you smarter:
Tiny organisms living naturally in the soil and carried in the air can actually make us more positive and alert when ingested or breathed in, say researchers from the Sage Colleges of Troy, N.Y.
At the 110th General Meeting of the American Society for Microbiology in San Diego today, scientists presented research that showed a particular bacterium increased learning abilities in mice when ingested. Studies had already shown that the bacterium could increase serotonin levels and decrease anxiety, but the researchers wanted to know if it could improve learning as well as mood.
